Does anyone know what the black cover on the opposite side of the gas filler is. It seems to be covering two holes and is not in line with anything.
I'm thinking of putting a radio microphone connection through it, but have no idea as to what it's actual purpose is

 

I'am not 100% sure but i know my dads 400 xt gas cap is on the other side from the side of where my 800xt is on maybe same rear fender just set up diff. do to the bigger eng. on the 800.

 

I been wondering the same thing... Maybe a aftermarket part we know nothing about? or just for looks, im not sure but I know what you are talking about. Heck man use it for what ever, thats what ill do if I find something for it.

 

And the answer is... I was at Sams, and they had a 400 outlander two seater and... on the left hand side was the gas cap and a fuel guage. so they must use the same rear plastics... the right hand side where my fuel cap is, had a nice black cover just like on the left hand side of mine.
